The present study investigated whether a p,p’-methoxyl-diphenyl diselenide (MeOPhSe)2-supplemented diet causes toxicity in rats. A second aim of this study was to determine whether a 10 ppm (MeOPhSe)2-supplemented diet has hypolipidemic effect on Triton WR-1339-induced hyperlipidemia in rats. To rule out the antioxidant property of (MeOPhSe)2in its hypolipidemic action, parameters of oxidative stress were carried out. Wistar rats were fed with 3, 10, or 30 ppm of (MeOPhSe)2-supplemented diet for 30 days. None of (MeOPhSe)2-supplemented diets caused alteration in general parameters of toxicity and lipid profile of rats. The hypolipidemic effect of 10 ppm of (MeOPhSe)2-supplemented diet on rats treated with Triton WR-1339 (400 mg/kg, intraperitoneal) was investigated. The (MeOPhSe)2-supplemented diet partially protected against the levels of total cholesterol (TC) and non-HDL-C and reduced the atherogenic index (AI) increased by Triton WR-1339 in rats. A positive correlation between TC and triglyceride levels (r = 0.679) and non-HDL-C levels (r = 0.929) and AI (r = 0.889) was demonstrated. Triton WR-1339 altered parameters of oxidative stress in livers of rats but (MeOPhSe)2-supplemented diet did not protect against these alterations. The results demonstrated that the hypolipidemic action of (MeOPhSe)2-supplemented diet is not directly related to its antioxidant property and devoid of systemic toxicity in rats at the parameters analyzed.

Ce travail a été conçu pour étudier l’effet d’un extrait riche en polyphénols de l’enveloppe charnue de l’amande douce sur le profil lipidique plasmatique chez la souris rendue hyperlipidémique par le Triton WR-1339 ainsi que sur la prévention de l’oxydation des lipoprotéines plasmatiques en comparaison avec le fénofibrate et l’hydroxyanisole butylé. On note que l’extrait phénolique réduit significativement le cholestérol total plasmatique de 58 % (p < 0,001) et les triglycérides de 62 % (p < 0,001). Par ailleurs, cet extrait réduit significativement le taux élevé du cholestérol-LDL de 61 % (p < 0,05) et augmente le cholestérol-HDL de 71 % (p < 0,05). Un tel extrait abaisse aussi significativement la valeur de l’indice d’athérogénicité de −72 % (p < 0,01) et celle du rapport LDL/ HDL de 55 % (p < 0,05). En outre, cet extrait possède un effet antiradical 2,2-diphényl-1-picrylhydrazyl dosedépendant avec une CI50 = 18,8 ± 0,55 μg/ml et inhibe significativement l’oxydation du plasma riche en lipoprotéines (CI50 = 13,8 ± 0,57 μg/ml). Nos résultats montrent que l’extrait est riche en polyphénols à caractère polaire (polyphénols totaux : 342,63 ± 3,44 mg/g, tannins : 144,67 ± 6,83 mg/g, flavonoïdes : 20,66 ± 0,92 mg/g) qui pourraient améliorer le métabolisme lipidique et prévenir l’oxydation des lipoprotéines et ainsi avoir un effet bénéfique dans la prévention de l’athérosclérose et des maladies cardiovasculaires qui en résultent.

The objective of this investigation was to test the hypothesis that the diabetes-induced reduction in lipoprotein lipase activity in cardiac myocytes may be due to hypertriglyceridemia. Administration of 4-aminopyrazolopyrimidine (50 mg/kg) to control rats for 24 h reduced plasma triacylglycerol levels and increased the heparin-induced release of lipoprotein lipase into the incubation medium of cardiac myocytes. The acute (3–5 days) induction of diabetes by streptozotocin (100 mg/kg) produced hypertriglyceridemia and reduced heparin-releasable lipoprotein lipase activity in cardiac myocytes. Treatment of diabetic rats with 4-aminopyrazolopyrimidine resulted in a fall in plasma triacylglycerol content and increased heparin-releasable lipoprotein lipase activity. Administration of Triton WR-1339 also resulted in hypertriglyceridemia, but the heparin-induced release of lipoprotein lipase from control cardiac myocytes was not reduced in the absence of lipolysis of triacylglycerol-rich lipoproteins. Treatment with Triton WR-1339 did, however, increase the heparin-induced release of lipoprotein lipase from diabetic cardiac myocytes. Preparation of cardiac myocytes with 0.9 mM oleic acid resulted in a decrease in both total cellular and heparin-releasable lipoprotein lipase activities. These results suggest that the diabetes-induced reduction in heart lipoprotein lipase activity may, at least in part, be due to an inhibitory effect of free fatty acids, derived either from lipoprotein degradation or from adipose tissue lipolysis, on lipoprotein lipase activity in (and (or) release from) cardiac myocytes.Key words: diabetes, plasma triacylglycerols, cardiac myocytes, lipoprotein lipase.

Statins should be used as a part of standard therapy in patients after heart transplantation. The effectiveness of statins is associated not only with their hypolipidemic action, but also with their immunomodulatory and antineoplastic properties. Statin therapy initiated early after heart transplantation improves the shortand long-term prognosis and outcomes, leading to a reduction in the incidence of cardiac allograft vasculopathy, acute rejection, and cancer.
